   net.sf.saxon.om.AttributeCollectionImpl

AttributeCollectionImpl
final public class AttributeCollectionImpl implements Attributes,AttributeCollection(Code)
AttributeCollectionImpl is an implementation of both the SAX2 interface Attributes and the Saxon equivalent AttributeCollection.

As well as providing the information required by the SAX2 interface, an AttributeCollection can hold type information (as needed to support the JAXP 1.3 javax.xml.validation.ValidatorHandler interface), and location information for debugging. The location information is used in the case of attributes on a result tree to identify the location in the query or stylesheet from which they were generated.



Field Summary
final public static  AttributeCollectionEMPTY_ATTRIBUTE_COLLECTION

public  AttributeCollectionImpl(NamePool pool)
     Create an empty attribute list.

Method Summary

public AttributeCollectionImpl(NamePool pool)(Code)
Create an empty attribute list.




Method Detail
addAttribute
public void addAttribute(int nameCode, int typeCode, String value, int locationId, int properties)(Code)
Add an attribute to an attribute list. The parameters correspond to the parameters of the net.sf.saxon.event.Receiver.attribute(intintCharSequenceintint) method. There is no check that the name of the attribute is distinct from other attributes already in the collection: this check must be made by the caller.

  value - The attribute value (must not be null)
Parameters:
  locationId - Identifies the attribtue location.
Parameters:
  properties - Attribute properties



clear
public void clear()(Code)
Clear the attribute list. This removes the values but doesn't free the memory used. free the memory, use clear() then compact().



compact
public void compact()(Code)
Compact the attribute list to avoid wasting memory



getIndex
public int getIndex(String qname)(Code)
Get the index of an attribute, from its lexical QName
Parameters:
  qname - The lexical QName of the attribute. The prefix must match. The index position of the attribute



getIndex
public int getIndex(String uri, String localname)(Code)
Get the index of an attribute (by name).
Parameters:
  uri - The namespace uri of the attribute.
Parameters:
  localname - The local name of the attribute. The index position of the attribute



getIndexByFingerprint
public int getIndexByFingerprint(int fingerprint)(Code)
Get the index, given the fingerprint. Return -1 if not found.

getLineNumber
public int getLineNumber(int index)(Code)
Get the line number part of the location of an attribute, at a given index.

Attribute location information is not available from a SAX parser, so this method is not useful for getting the location of an attribute in a source document. However, in a Saxon result document, the location information represents the location in the stylesheet of the instruction used to generate this attribute, which is useful for debugging.
